A big caterer in Germany has his own air handling unit Airbox from Rosenberg that reaches an air flow of 21.000 m3 per hour and has been installed in the top of the building. This AHU has been designed to strictly comply with the German VDI 2052 and VDI 6022 directives governing the minimum conditions for ensuring a healthy environment and is equipped with:multi-stage filter units a highly efficient heat recovery system to further utilise the actual heat of the "waste product" in commercial kitchens in an energy-efficient manner components of the highest quality to withstand ...

Airtècnics have updated their air curtain selection program, which is available online. The enhancements include all the innovations in air curtains achieved, with a wide variety of customization options, accessories and finishes, with a more visual and intuitive design for all devices. This is a very useful tool that allows users to select the most appropriate air curtain for a specific installation.  The first step requires basic installation data:door dimensions type of installation (vertical/horizontal) heating optionsThis enables the program to ...

How does an EC motor work? The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The stator is driven by electronic switches controlled by a microcontroller. The motor needs to be supplied with AC voltage and a DC voltage signal to operate.The mains voltage, namely the alternating current (AC), is rectified by the electronic commutation of the EC motor. A downstream inverter supplies the motor voltage via the direct current (DC) signal in accordance with the specified load. In contrast to the AC ...

Among the Airtècnics solutions is the renovation or incorporation of custom ventilation systems. Today we are dealing with a real case in Germany, in the Ruhr area, in the west of the German country, where an air handling unit has been installed in a large restaurant.    The model chosen by the restaurant was the Airbox F40 without frames. A very light weight was required, but it was essential that the sound values ​​were low. In addition, the units had to be very compact, because there was very limited installation space. The instalation is composed by two ...

Data centers produce a lot of heat, which is one of the problems they cause and one of the most important to eradicate. Energy-efficient EC fans help to reduce operating costs and are part of an economical and environmentally friendly cooling concept.    Most of the energy consumed by data processing centres goes into cooling and conditioning the environment surrounding these electronic devices. Data centres are spaces in which an organisation's information is stored and processed, and these spaces can be as large as a building, occupy basement rooms or be the size ...

Air curtains are an effective solution to various problems that arise depending on the scenario. It is well known that air curtains are useful to avoid draughts and as an energy saving system. Moreover, Airtècnics adds advantages by means of the anti-insect system of the air curtains. Catering businesses can attract insects such as flies or mosquitoes due to the fact that their raw material is organic. Fruit, vegetables, meat and fish, as well as food waste, are a source of attraction for these living beings that are not only annoying, but can also mean a public health ...

Airtècnics puts at your disposal the new Rosenberg Dplus diffuser. This axial fan diffuser is a suitable solution for converting dynamic pressure into static pressure. Due to the constant expansion of the cross-section, the velocity in the air flow direction decreases and the losses are converted into usable static pressure.  On the one hand, the static pressure gain makes it possible to reduce the drive power of the fan, thus reducing the operating costs of the fan. On the other hand, the static pressure gain can also be used in such a way that the fan delivers ...

Most of us have heard of "The Little Mermaid", "The Tin Soldier" or "The Ugly Duckling" since we were children. These are just three titles from Hans Christian Andersen's oeuvre of more than 200 stories for children and adults. And the museum that has been erected in his honour has become a magical space for children and adults alike since the summer with the latest technology in its facilities, such as air curtains.    The museum is the lungs of Odesen, the birthplace of the most prolific and renowned author in the history of Danish literature. The gardens are the ...

In an explosive ambient caused by flammable gases, mists, vapours or combustible dusts, electronic components play a crucial role in the possibility of generating an explosion or ignition. Air curtains or any electronic device that is part of such a hazardous installation must be fully protected to ensure that people or the environment are not exposed to the danger of an explosion. ATEX fans: solution for explosive atmosphere ATEX motors comply with ignition protection measures. This type of protection is characterised by the fact that it prevents the possibility of high ...

Maxwell air curtains, which until now have been served with AC fans, can now be manufactured with energy-saving EC fans. This makes it a highly efficient industrial air curtain with increased flow and power. EC motors are a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The AC mains voltage is rectified by electronic commutation of the EC motor. A downstream inverter provides the motor voltage as a function of the load, similar to the principle governing a frequency converter. EC motors have the advantages of both motors. They are more ...

In Airtècnics we never stop our innovation eagerness and as a last contribution to make our ventilation devices more durable, we add to the catalogue of finishes a special anti-corrosion paint on request. It can be applied by spraying, flow or immersion and does not contain toxic gases, it is totally environmentally friendly. Flow application ensures 100% penetration into the coils of industrial chillers and AHUs with no limitations on dimensions and number of rows.    Spray application covers RTPF type coils up to 6 rows and full coverage of MC type coils. ...
